I am trying to find examples where Mathematica is used to study dynamic equations through the use of phase portraits, including their respective points: equilibrium, stability, attractors, bifurcations and so on.
Does any one have any work on this subject that he/she would mind sharing? I had many courses in this field in graduate school in the early 70's, and now I am trying to get a handle on them again. Back then I was using Fortran. Things have changed a lot.
